Don-Jo AST-21382 Security Strike – 1-3/8" x 18", 13 Gauge Steel, Two Latch Holes

The Don-Jo AST-21382 Security Strike is a heavy-duty, 13-gauge (.095) ferrous steel security strike measuring 1-3/8" wide by 18" tall — purpose-built to reinforce the strike area of commercial and residential door frames where extra protection against forced entry is required. Manufactured by Don-Jo Manufacturing, this security strike features two latch holes on 3-5/8" or 4" centers, making it compatible with standard double-hole door frame preparations common in both new construction and retrofit applications. Available in three finishes to match your hardware schedule: silver lacquer (SL), bright brass (BP), and white (WH). When a standard strike plate is not enough and a full-length security strike is the specified solution, the AST-21382 delivers the steel thickness and coverage that frame reinforcement demands.

AST-21382 Security Strike Key Features

• Full 18" Coverage: The tall 18-inch face plate spans well beyond a standard strike box, distributing load across a greater length of the door frame to resist door frame deflection.
• Heavy 13-Gauge Steel Construction: Formed from 13 ga. (.095) ferrous steel — substantially thicker than lighter economy strikes — this security strike is built for commercial-grade frame reinforcement.
• Double Latch Hole Configuration: Two latch holes on 3-5/8" or 4" centers accommodate a wide range of latching and deadlatching hardware preps without special modification.
• Three Finish Options: Order in silver lacquer (SL), bright brass (BP), or white (WH) to coordinate with the surrounding door hardware and frame finish.
• Compact Width for Standard Frames: At 1-3/8" wide, the AST-21382 fits neatly into standard commercial frame strike pockets without requiring frame modification.
• Convenient Shelf Pack: Sold individually through DoorwaysPlus; packaged from the factory in shelf packs of 10 for contractor and distributor ordering efficiency.
